Abstract: In this paper, according to the calculation example of air-to-air missile powered by a two-stage solid rocket motor, the integral optimum design of missiles with solid rocket motors is studied.Therefore,the energy model, the mass model of solid rocket motor and the mathematical model of missile and objection are established,and the optimization of nine design variables are conducted successfully based on the optimization theory. The gross weight of missile reduces by23.3kg. the optimization results show that the models established are correct.

Key words: Missile;Solid rocket engine;Optimum design
